16S rDNA PCR-RFLP patterns of chromosomal extracts from bacterial isolates recovered in South Bass Island groundwater after DdeI digest. Lane 1, 100-bp marker; lane 2, C. jejuni control (ATCC no. 11168); lanes 3–9, samples isolated from South Bass Island groundwater sites PB-5, PB-12, PB-3, PB-6A, PB-6B, and PB-6C, respectively. DdeI restriction fragments of 421, 353, and 183 bp are indicative of Arcobacter as specified by Marshall et al. (1999).
